I expect that REDIRECT will be the required way for FTP at present, since TPROXY has requirements that there is a client socket state to associate with the non-local binding. Essentially that sockets are opened directionally in sequence client->proxy->server - whereas FTP data connections are opened in the opposite sequencing order: server->squid first, then squid->client.
